In the reaction CO+Cl2 yields COCl2, what is the ecell for the reaction?
Accepted Answer
In the reaction CO + Cl2 → COCl2, assuming the standard reduction potentials for the half-reactions:
Cl2 + 2 e- → 2 Cl- (E° = +1.36 V)
CO + 2 e- → C + O2- (E° = -2.29 V)
The electromotive force (EMF) or cell potential (Ecell) for the overall reaction can be calculated using the equation:
Ecell = E°(reduction) - E°(oxidation)
Ecell = (+1.36 V) - (-2.29 V) = +3.65 V
Therefore, the Ecell for the reaction CO + Cl2 → COCl2 is +3.65 V.
